HOSE-COUPLING.

Specication of Letters Patent.

Patented J an. 8, 1918..

Application led July 12, 1916. Serial No. 108,949.

To all whom t may concern.'

Be it known that I, Cassius M. CLAY, a` citizen of the United States,and resident of Mexico, ll'lissouri, have invented certain new anduseful improvements in Hose-Couplings, of which the following is aspecification containing a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part hereof..

My invention relates to improvements in hose couplings and the object ofmy improvements is to construct a coupling comprising members whichinter-hook and which is provided with a locking means againstuncoupling, a portion of the locking means conforming with the externalsurface of the body of the coupler in order to prevent its being caughtand released by engagement with other objects and the inter-hookingportions of the members arranged to be interengaged from one end only toassure the proper working of the locking means.

With the above and other objects in view which will be hereinafter madeclear my invention consists in certain novel details of the constructionand arrangements of parts which will be hereinafter fully, clearly andconcisely set forth in my specification, pointed out in my claims andillustrated by the accompanying drawings, in which- Figure 1 is a planof the complete coupling;

Fig. 2 is an end View showing the meeting face of one of the couplingmembers;

Fig. 3 is a view similar to Fig. 2 of the other coupling member;

Fig. Ll is a longitudinal sectional elevation of the two memberscoupled;

Fig. 5 is a transverse sectional elevation of the coupling member shownin Fig. 3 taken through its locking element;

Fig. 6 is a plan of one of the coupling members with a portion of thehose stem broken away and the locking element removed.

F ig. 7 is an elevation of the members shown in Fig. 2 with a portion ofthe hose stem broken away, and

Fig. 8 is a longitudinal sectional elevation taken on the line 8*-8 ofFig. 6, the locking device and the expansible gasket being removed.

Ieferring by numerals to the accompanying drawings, 9 and 10 designatethe body portions of the two coupling members, the portions of whichnext their meeting faces are cylindrical, the remaining portions that isthe portions next the hose stems are chamfered or frusto-conical. Formedintegral with each members 9 and 10 and extending outwardly from thefrusto-conical portions are the hose stems 11 each of which bearsadjacent the frusto-conical portion an annular flange 12 whereby tofacilitate the securing of a section of hose to the stem. The bodyportions of the stems beyond said flanges are serrated as is common.Formed through each stem and concentric therewith is a bore 13 andformed through the bodies of the members 9 and l0 are the bores 14.

The reference numeral 15 designates a cavity formed in the meeting faceof the member 10, concentric with the bore 14 but eccentric to the bodyof the member, the inner end of said depression having greaterdiametrical dimensions than the outer end forming an inclined shoulder16.

The reference numeral 17 designates an expansible gasket the outersurface of which is shaped to conform with the depression 15 in themember 10, the gasket having at its innermost end a peripheral ange 18,engageable to the rear of the shoulder 16 of the member to preventunseating of the gasket when pressure is applied to the fluids whenpassing therethrough. This gasket 17 is of ring-like formation, itsinner surface having therein a depression which forms a lip 19 arrangedto be acted upon by fluid under pressure to be forced outwardly beyondthe face of the coupling member 10, to engage with and form a leak-tightjoint with the meeting face of the companion member 9. By thisarrangement of gasket the gasket will normally lie wholly within thedepression formed in the coupling member but be expanded, that is thelip 19 beyond normal dimensions when a fluid pressure is acting upon thelip.

As shown in Fig. l the body portion 9 h as projecting inwardly therefroma head 20 extending in one direction the full diameter of the member andin the opposite direction less than the diameter of the member. Alongeach side of the projecting head and next the meeting face of the memberis a flange 21 forming next the body of the member a channel 22, thesechannels being open at their tops but closed by the shoulders 23 attheir bottoms.

Formed through the body of the member 9 is a bore 24 paralleling theaxis of the member and open at both ends. Extending outwardly from thebody portion of the member l0 are the spaced heads 25-25,` the spaceintervening between the said heads being of the same dimension as theheadof the member 9 the heads 25 and head 20- v forming kintegralcontinuities-of 'the 'bodies of the members 9 and 10. AS clearly shownin F ig. 3 the heads 25V have in their inner faces the channelsr26forming lianges 27 eX- tending only a portion of the lengths of the4heads so that when the tivo coupling mem-1 bers are to be coupled theinter-engagingY flanges 2l and 27 are only inter-engageable inonedirection, the stops or shoulders 23, togetherV with the stops orshoulders 28Y 'limiting the sliding movements of the twoI members incoupling in order to bring the members i-n perfect relativeregistration.

In the top of the member l() there is..

Y formed a cavity 29 parall'eling the aXis of the member and having itsside Walls 30 under-cut as clearly shown in Fig. the oneV said Wallhaving a notch 3l therein.

The reference numeral 32 designates a y sliding block arranged formovement in the 'n depression 29 vand between the Walls 30 thereof, thisblock having its side shaped to conform with the depression and havingvdove-tail connection withv the member the block is prevented from movingradially Vrelative to the member 10 but is vcapable of axial movementsrelative to the member, the Y outer or upper surface of the block being`shaped to conform with the cylindricalbody ofthe member l0. Y

AsV clearly shown in Fig. if the block has formed therein a bore 33arranged to receive an extensile coil spring 34 the one endof whichimpinges the block to normally hold itwith its one end in registrationwith the meeting face of the member lOV itsy otherv end impingingtherear Wall of the cavity 29. At-the forivard end of theblock there isl alatch 35 the outer face of which is beveled to facilitate its seatinginto the end ofthe boreu2etivhich bore forms Withsaid latch the lockforv securing the coupling members against yuncoupling the inclined faceofthe latchymaking the locking of the coupling members automatic.` ,n

By reason of the bore 242being open at v bothends the likelihood Yof itsbeingrilled tion oftheblockV and prevent its being Wholly disengagedfrom the member l0.

lt;\vill be.. apparent from the construction illustrated and as justdescribed that the `cylindrical formation of the coupling memberstogether with the locking elements therefor 'reduce to a minimum thelikelihood v .coupled in one direction only in order to properly relatethemembers to the locking iechanism so that the lockingv device Willautomatically operate. r

I.L have shown the boresrlt through the bodies of the couplingy memberstoi be nonalined with the boresglofthe stemsof the vcoupling members,which expedient permits theV placement of the gasket 17 and the slidingblock 32 carrying the latch 35 in a coupling member ofminimumdiametrical dimensions. s

Havin-gthus described my invention what I claimasneiv thereinand desireto secure by lLetters."fatent vfof .the United States, therefor is- .Y 1I l. A cylindrical hose coupling member having a bore therethrougheccentric'tothe-4 b'cdy of the member and a cavity inits end concentricWith the bore, a .gasket arranged in said cavity and a latchcomprisingan element arranged for -InOVeinent lengthwise of the r member Within.the peripheral, uninter-A rupted cylindrical. surface of'l the member--`2'. A hose coupling comprising a pair -of membersz havingend portionsofsubstantially vcylindricali formation and. ofsmoothuninterrupted,-exterior, and having their meetingtendsunterengagingpdevices, .and a lock forholding said devices inengagement comprising. al seat 'in the, meeting facer-ofV one member,.an element-arranged for. movement ,lengthwiseof.tlie other member,having its outermost face exposed throughoutjits length .and shaped to,conform with the periphery of the` coupling member, ,aspring forholding; theelement to its onek limit of @movement andy a latchcarriedthereby for insertion in Said seat,` substantially as shown andV forthe; purposes stated.
